Upsource 2020.1 Help

Error: "Could not initialize class com.sun.jna.Native"

The error occurs on the Cassandra database startup. Cassandra throws the following exception while starting:

ERROR o.a.c.service.CassandraDaemon - Exception in thread Thread[MemtableFlushWriter:1,5,main]

java.lang.NoClassDefFoundError: Could not initialize class com.sun.jna.Native

at org.apache.cassandra.utils.memory.MemoryUtil.allocate( ~[apache-cassandra-2.2.4.jar:2.2.4]

at<init>( ~[apache-cassandra-clientutil-2.2.4.jar:2.2.4]



This issue is typically caused by a noexec flag set on the temporary directory.

There are two possible ways to resolve the issue:

  • Remount the tmp directory without the noexec flag.


  • Configure Cassandra to use another location as a temporary directory. To do that...

    ... for a ZIP installation:

    1. Stop Upsource: <upsource_home>/bin/ stop

    2. Run the following command:

      <Upsource_home>/apps/cassandra/bin/ configure$HOME
    3. Start Upsource

    ... for a Docker installation:

    1. Stop Upsource: docker exec <containerId> stop

    2. Run the following command:

      docker run -it -v <path to data directory>:/opt/upsource/data \ -v <path to conf directory>:/opt/upsource/conf \ -v <path to logs directory>:/opt/upsource/logs \ -v <path to backups directory>:/opt/upsource/backups \ -p <port on host>:XXXX \ --entrypoint=/bin/bash jetbrains/upsource:<version> \ /opt/upsource/apps/cassandra/bin/ \ configure$HOME
